function default.notStrictEqual

Usage in Deno

```typescript import mod from "node:node__assert.d.ts"; ```
notStrictEqual(
actual: unknown,
expected: unknown,
message?: string | Error,
): void
Tests strict inequality between the `actual` and `expected` parameters as determined by [`Object.is()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is). ```js import assert from 'node:assert/strict'; assert.notStrictEqual(1, 2); // OK assert.notStrictEqual(1, 1); // AssertionError [ERR_ASSERTION]: Expected "actual" to be strictly unequal to: // // 1 assert.notStrictEqual(1, '1'); // OK ``` If the values are strictly equal, an `AssertionError` is thrown with a `message` property set equal to the value of the `message` parameter. If the `message` parameter is undefined, a default error message is assigned. If the `message` parameter is an instance of an `Error` then it will be thrown instead of the `AssertionError`.

Parameters

actual: unknown
expected: unknown
